Incorporated Fixed Resistor
A fixed resistor can be incorporated in the Series 110
at the end of CW or CCW rotation to a minimum of 10%
of the total resistance. The rotation is shortened by an
amount proportional to the ratio of the fixed resistor to
the total resistance. Available at extra cost.

Resistor Adjustment
Standard Cross Slot: Provided in drive plate for screwdriver
adjustment.
Special Molded Knob: Available at extra cost secured to
drive plate cross slot.
Mounting Types Available
Type 110: Solder or clinch-ear mounted
Type XPC-110: Vertically mounted on printed circuit board
Type 111: Snap-in mounting
Type 112: Eyelet or rivet mounting
Rotational Torque
1/2to 10 inch ounces (36 – 720 g-cm)
Terminals
Terminals at end of CW or CCW rotation may be omitted.
Refer to terminals on all types by numbers 1 and 3 as
indicated on line drawings.
